370z 7AT - Need Suggestions/Advice

Leroydsouza

lol
Estimate Quotation for Just TT and transmission replacement is around (With Shipping, Base Products)
20k.

Alternative being Stillens supercharger, Would i need to rebuild transmission or will Valve body upgrade be reliable enough ?
Would i be near 450 whp atleast ? i understand that supercharger has its limitations but what would it max out at ?
My driving is a bit on the hard side ..i hardly ever go over 180km/h but i am usually hard on the 0-140. But my first gear will be taking some stress i guess. Does this mean i am required to build the transmission ?

If i am building the transmission, Thn i would go TT, If not stillen seems reasonable enough for me to settle
20k though just getting them to me lol

Hey Leroydsouza,

I'm running Aam competition TT with a valve body upgrade. I'm at 480whp and the transmission shifts and feels solid.

If you go with the stillen kit you won't have any room to grow. If you do try to get 450whp from it you risk popping the motor.

Leroydsouza

Thats good to know but

main concerns,

1) Do you push it on first gear ?
2) Your 5,6,7 gears are weak i am sure so how do you drive, Manual mods or ?
3) How long have you had it and have you checked for any damage to the tranny ?
4) It is a cheaper option to get the valve body upgrade and the turbo but

reiability . tsk tsk.

have you tracked the car ? Quarter mile timing ?

1. Yes, but it doesn't take much to spin the tires on 1st-3rd.

2. On the freeway, I keep it on manual mode and 5th can handle a bit boost. I never hit 6th and definitely not 7th.

3. I recently had it installed. Picked it up late November and have no reason to check the trans. I do plan on building the tranny sooner or later

4. I had the same dilema about reliability but if that's your goal stay stock. Adding boost to any car that's not designed for it.... Well have some oh sh*t money just in case.

I haven't tracked it yet. I want to do my diff to help with traction and my re-11s hate the cold.

Contact Max at aam competition, great guy and he can steer you the right way.

Leroydsouza

Thats reassuring.

I totally understand that i cannot have factory reliability.
However spending money should be able to get me there ? or so i hope.

Well its nice to know that you do have it installed ..and by the time i am ready for it, Ill definitely have better answers from you.

Hopefully by the end of this year , Ill go with TT.
Till then i need to figure out how to get this transmission part done right.
I have spoken to both Level 10 for the tranny and Someone at AAM too.
Just narrowing it down and getting my supporting mods done right i guess.

Stock isnt an option.

After boosting the z it became a totally different beast! Hope I helped and best of luck with your build

My Stillen is at 418whp/312tq and I have been beating one the 7AT for over a year with no problems. The only thing done to mine is a Stillen trans cooler and adjusted the pressures in uprev so it shifts faster at high rpms. The only reason I'm thinking I'm buying the Level 10 is that I'm planning a lot of track days this year.

Leroydsouza

Decided to go with Fast intentions.
But i am definitely going to rebuild the transmission, because i am one of those mad drivers and will not be able to pay attention to what gear and what speed i am running at. i have a heavy foot and i would prefer my transmission dont give up on me.

Thanks for all your help guys, You did narrow my search

Also, Ill be changing the mufflers to straight dual. I hope that works out, I dont really want to order a complete new CBE.
Shipping Hurts

Straight pipe will be awesome on a turbo setup. Turbo is hell of a muffler

Will just the muffler part do the trick ?

I will change only the muffler part
Hopefully to Fast intentions mufflers ?
Will that be umm perfect ?

I fired mine up with just straight pipe, no muffler, and loved it. If I hadn't of already bought the exhaust I would have left it that way
